High nitrogen enrichment buffers plant photosynthesis against herbivory damage
Functional Ecology, Volume 40, Issue 1, Page 229-238, January 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivorous insects and nitrogen deposition are key drivers of ecosystem productivity under global change. However, their combined effects on plant photosynthesis, particularly during insect outbreaks, remain poorly understood in natural ecosystems.

Vulnerability of tropical fish communities across depth in the central Indian Ocean
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Zhongguo shiyan zhenduanxue, 2020 IgA肾病(IgAN)是1968年由法国学者Berger和Hinglais首先描述和命名的,其病理特征是光镜下常见弥漫性系膜增生或局灶节段增生性肾小球肾炎,免疫荧光可见系膜区IgA或以IgA为主的免疫复合物沉积,因此也称为Ber-ger病(Berger’s disease)[1]。IgAN可以发生在任何年龄,但80%的患者在16-35岁之间发病,

Shuitu Baochi Xuebao, 2017 通过大田试验，探讨了全膜覆盖下不同滴灌量对河套灌区玉米关键生育时期光合特征、产量和水分利用效率的影响。结果表明：（1）除拔节期外，高、中滴灌量处理下玉米叶片净光合速率、蒸腾速率和气孔导度均显著高于低滴灌量处理（P＜0.05），而高滴灌量与中滴灌量处理之间无显著差异；（2）低滴灌量处理下的玉米叶片光合水分利用效率在其他生育时期均显著高于高滴灌量处理（P＜0.05），并且高滴灌量处理下玉米光合水分利用效率在拔节期显著高于其他生育时期；（3）不同滴灌量下，玉米叶片净光合速率、蒸腾速率 ...

New Phytologist, Volume 247, Issue 1, Page 144-159, July 2025.Summary Domesticated chickpea cultivars exhibit limited genetic diversity. This study evaluated the effects of chickpea domestication on phosphorus (P)‐use efficiency (PUE) under low‐P conditions, using a diverse Cicer collection, including wild species. Two wild Cicer species – 54 C. reticulatum accessions and 15 C. echinospermum accessions, and seven

Shuitu Baochi Xuebao, 2017 为揭示镉（Cd）富集植物龙葵的Cd吸收、积累与光合生理特性间的相关性，采用室内盆栽试验，在不同Cd添加水平下（0，2，5，10，20 mg/kg，分别记为Cd0、Cd2、Cd5、Cd10、Cd20），研究了龙葵对重金属Cd的吸收、积累特性及生理响应。结果表明：龙葵对Cd有极强的耐性，在Cd浓度为20.0 mg/kg的污染土壤中仍能正常生长；Cd≤10.0 mg/kg的污染土壤中龙葵对Cd的富集、转运系数均大于1；但Cd20处理龙葵对Cd的富集和转运能力显著下降。Cd在龙葵中的分布为地上部>地下部 ...

Uncovering Xi Jinping's Policy Agenda: Text As Data Approach
The Developing Economies, Volume 63, Issue 1, Page 9-46, March 2025.How many agendas has Xi Jinping put forth and promoted since taking office in 2012, and what are the types of agendas? How much of political attention has each agenda received, and how has the allocation of attention changed over time? We utilize a dataset of presidential statements, speeches, and reports from 2012 to 2022 and employed automated text ...

Guangtongxin yanjiu, 2009 文章基于耦合模理论,采用传输矩阵法数值分析了光栅折射率调制对光纤Bragg光栅（FBG）特性的影响。结果表明:随着折射率调制深度的加深,光栅的反射谱峰值波长发生蓝移,峰顶变得平坦;光栅时延的最小值发生在光栅的Bragg波长处;峰值反射率增大,峰值半宽（FWHM）呈线性变化。
